Referring more particularly to the separate parts of this invention as embodied in the form shown in the drawings (Fig. 21), 1 indicates numeralkeys and2 character keys, which deprem key-levers 3 to rock bell cranks 4 and swing type bars 5 up against the front side of a platen 6 carried by a carriage by-step movement by means of a spring barrel, not shown,under the control of'an escapement mechanism indicated'in general at hls-escapement mechanism includes a "rack 8, adjustably mounted on the carriage 42, so as to normallyengage with a pinion 9 connected to an escapement wheel 10. This escapement wheel 10 iscontrolledyin its movements, so as to give a step-by-step movement to the carriage 42, by a pair of pawls 11 and 12, one of which is fixed and the other of which is movable. These pawls 11 and 12 are mounted on a universal frame 13, so as to come alternately into engagement with the esoapement wheel 10 when any one of the keys 1 and 2 is actuated.

his is accomplished by a heel 14 on each of the type bars 5 coming into engagement with a universal bar 15 on the universal fran1e 13. The universal frame 13 is supported for its back-and-forth movement by one or more arms 16, to which they are pivotally connected at 17, the latter being in turn pivoted at 18 to any suitable portion of the typewriter frame.

The computing mechanism includes numeral keys 19, which act as described in my above mentioned application, to cause the limiting the return movementof The carriage 42 is given a step rotation ofa shaft 20 from a shaft 21 by means of a complete gear 22' and a mutilated gear23, amounts corresponding to the particular numeral keys actuated. Connected to each of the mutilated gears 23, there is provided a one-tooth gear 24, which is arranged to rock a lever 201 to pull on a link 202, and thus draw down the associated one of the typewriter numeral keys 1 against the tension of a spring 203. The particular details of this mechanism are not essential to this invention, but may be the same as that shown and described in my above-mentioned application. The numeral 25 designates generally the totalizers' or registers which are mounted upon a suitable support 26 and each of the number bearing members of the totalizer or register is provided with a gear 27 by means of which motion may be imparted to the number bearing members. A carriage 28 is mounted upon the base 29 of the mechanism so as to be reciprocated transversely thereof between suitable guides 30. Traveling actuating mechanism, desiggenerally by the reference numeral 31, is supported by the carriage 28 to move therewith and the actuating mechanism embodies operating gears 32 for imparting motion to the gears 27. These gears 32 are connected with a shaft 33 and a gear 34 is also provided on the shaft 33 which gear receives its motion from a drum or toothed cylinder 35 through the medium of interme-,

diate gears 36.

he carriage 28 with the supported mechanism is adapted to be moved by means of an arm or lever 37 which is pivoted intermediate its ends as at 38 upon the. base 29.

his arm or lever 37 is preferably provided at one end with a toothed segment 39 which meshes with a rack 40 carried by the carriage 28 so that when thearm or lever 37 is moved about its point of pivotal support 38 the carriage 28 will be correspondingly ad'- justed or moved to change the denominational relationof the gear 32 with respect to the gears 27 of the totalizers or registers 25. i

All of the above described mechanism, however, forms no part of the present invention but constitutes a portion of the subject matter of the application above referred to.

The typewriter 41, which is shown in Figs. 17 and 21, is preferably supported at an elevation above the base 29 and the carriage 42 thereof is provided with a rack 43 the shaft 45 lever37 through the medium of the connecting mechanism which will .now be described, so that the arm or lever 37 will move about its point of pivotal support in. accordance with the movement of the typewriter car riage and thereby advance the traveling actuating mechanism 31 of the totalizers or registers. I

Mounted loosely upon the shaft 45 (see particularly Figs. 8, 10, 14, 16 and 17) and preferably adjacent the base 29 of the machine is a gear 47 which meshes with a toothed segment 48 on the other end of the arm or lever 37 which is adjacent thereto, and this gear 47 is connected to the shaft 45 for rotation therewith through the medium of a clutch, whichclutch will lock the gear to the shaft when the shaft is rotating in one direction and which may be rendered inactive to permit the gear or the shaft to be rotated in the opposite direction and independently with respect to each other according to whether the typewriter carriage is returned independently with respect to the traveling actuating mechanism of the tota'lizer or vice versa. This clutch mechanism comprises a clutch member 49 (see particularly Figs. 6 and 8) which is sleeved upon the shaftz45 and is preferably keyed as at 50 to the shaft for rotation therewith. The clutch member is providedwith a base 51 having a beveled or inclined face 52 and this inclined face is located some distance above the bottom of the base 51 sothat a smooth peripheral edge 53 will be provided for a purpose to be set forth. The clutch .melnber above the inclined face 52 is preferably enlarged as at 54 and this enlarged portion is provided with a notch 55 to form a shoulder 56 (see particularly Figs. 6 and The body of the clutch member 49 above the enlarged portion 54 is preferably reduced as at 57 and this reduced portion The periph-v ed may be of any desired height. ery of the reduced portion is provi with spaced circumferential flanges or rings 58, f0r apurpose to be set forth. Secured to the gear 47, preferably the upper face thereof and for rotation therewith, is a support 59 (see also Fig. 16), which preferably extends under the base 51 of the clutch member 49, and this support- 59 is provided with extensions 60 projecting above the base and on opposite sides of the clutch member 49. Pivotally mounted upon each of the extensions 60 is a dog orpawl 61 which are arranged on opposite sides of the clutch member 49 and are disposed in opposite directions. The extensions on'the support 59 are of such a height that when the clutch member 57 is in an operative position so as to rest upon the support 59 betweenthe extensions 6.0, to lock the shaft- 45 and gear 47 together, the extremities of the dogs or pawls is caused to control the arm or ing right to left, the shaft 45 which is connected 61' will engageland rest against the periphery of the enlarged portion 54 of the clutch member, and elastic members 62 are provided for each of the dogs or pawls 61 which tend normally to hold the extremities thereof into engagement with the periphery ofv the portion 54. v

The movements of the traveling actuating mechanism while controlled totake place step by step with the corresponding advancing movement of thetypewriter carriage, are not effected by the carriage itself positively moving the traveling actuating mechanism. There is provided, however, a separate motive means for the traveling actuating mechanism, which normally tends to move the traveling actuating mechanismstep by step in an advancing direction but is retarded by the carriage, which, however, as' it moves along permitsa corresponding movement of the actuating mechanism, which is forced by its separate motive means to follow the movements of the carriage just as soon they are made. The means for doing this will now be described.

It will be manifest that as the typewriter carriage advances when the machine is beoperated, in the usual direction, "from therewith will rotate in cated by the arrow in Fig. be manifest that'in order traveling actuating mechanism in the same direction, the gear 47 which is connected with the arm or lever 37 mustbe rotated in a similar direction or in the direction indicated by the shoulder 56on the clutch member 49 is the direction indi- 14. It will'also to advance. the

so arranged that a rotation of the clutch member by the shaft 45 would tend to move the shoulder away from the adjacent dog or pawl 61, the gear 47 would remain idle inasmuch as it is loosely mounted on the shaft 45. Therefore in order to impart a rotation to the gear 47 inthe same direction as the rotation of the shaft 45, suitable mechanism is provided and which mechanism will also tend to hold the extremity of one of the dogs or pawls 61 in engagement with the shoulder 56. Any suitable means may be provided for accomplishing this result but a suitable and efficient means comprising a motor will now be described.

A gear 63 preferably of the bog; type having a chamber 64 is journaled on a suitable axle 65' (reference being had, particularly to Figs. 14 and 16). This axle 65 is mount ed in a suitable support 66 and the gear 63 is adapted to rotate loosely thereon. This gear 63 meshes with the gear 4.7 and a spring 67 is arranged within the chamber 64 with one extremity 68 anchored to the wall of the chamber and he other extremity 69 is thearrow in Fig. 14, but as anchored-to the axle 65 within the chamber.

The spring 67 is coiled about the axle 65 connection with the shaft that its normal tendency will be to rotate the gear '63 in the direction indicated by the arrow in Fig. 14 and this movement of the gear 63 willtend to move the gear 47 in the direction indicated by the arrow in Fig.-14 and consequently th support 59 in a direction that the extremity of the dog or pawl 61 adjacent the shoulder 56 will be held in engagement with the shoulder, and the support 59 and the dog or pawl 61 will follow the clutch member 49.

It will therefore be seen that the clutch just described will form a loose connection between the gear 47 and the shaft 45, that is to say, a connection which will cause the gear 47 to rotate in the same direction as the shaft 45, and will also permit either the shaft 45 or the gear 47 to be moved in the opposite direction one with respect to the other. The traveling actuating mechanism being connected with the gear 47 may also be returned to its initial or starting position independently with respect to the typewriter carriage 42. Vi heu the traveling actuating mechanism is thus returned, the dogs or pawls 61 will ride over the periphery of the enlarged portion 54 of the clutch member 49, the elastic members 62 actuating to cause the extremity of one of the dogs or pawls 61 to move into engagement with the shoulder 56 when the direction of movement of the dogs or pawls with respect to the clutch mem r 49 is reversed. An arm (see Figs. 3 and 16) may be provided on the axle 65 and which arm engages a stop 71 in order to hold the axle 65 against rotation under the tension of the elastic member or spring 67, and may be used to obtain an spring 67 in setting up the machine.

The typewriter carriage 42 is adapted to be automatically returned to its initial or starting position from any point to which it has been advanced and in order that this return may be effected at the will of the operatorsuitable mechanism for accomplishing this result will now be described. A shaft 72 is mounted in suitable bearings 73 so as to extend transversely with respect to the upright shaft 45 and this shaft 72 has 45 (see particularly Figs. 3, 16 and 17) through the medium of a beveled gear- 74 on the shaft 72 which meshes with a companion gear 75 on the shaft 45. 'A gear 76 (see particularly in such a manner Figs. 3 and 4) is secured to the shaft 72 for rotation therewith, preferably at one end of the shaft and some distancev from the gear 74. This gear 76 meshes with a gear 77 preferably of 'a larger diameter and which gear 77 is secured to a shaft 78 for rotation therewith, the latter being journaled in suit able bearings 79. A-gear 8O is-also secured to the shaft 78 for rotation therewith and meshing with this gear 80 is a toothed segend 84 of the arm or ably terminates adjacent initial tension on the .not necessary to illustrate.

ment 81, which latter is formed on the end of an arm or lever 82 pivotally mounted intermediate its ends as at 83 to move'about a horizontal axis so that the segment 81 will move in an upright plane, 'The free lever 82 projects for some distance beyond the pivot 83 and is )referably bifurcated as at 85 see particularly Fig. 3) across which bifurcation a pro jection 86 extends and if desired an antifriction roller indicated in dotted lines at 87 in Fig. 4 is journaled on the projection 86. The extremity 84 of the arm 82 prefera shaft 88 which is journaled in suitable bearings 89 and secured to this shaft 88 for rotation therewith is a cam 90, which latter is so arranged as to project into the bifurcated portion 85 of the arm or lever 82 so as to permit the free end of the arm. or lever to be moved toward or away from the axis of rotation of the cam and to' permit the periphery of the cam to engage the anti-friction roller 87 when the cam is rotated to force the free end of the arm or lever 82 away from the axis of rota tion of the cam and therebylowerthe segment 81 to rotate the gear 77 in oiie-direc-' tion. The gear 77 isrotated in thejiipposite direction by the advancement ofthe typewriter carriage which will rotate the shaft 45 and the gear 75 thereon. This gear will impart its motion to the gear 74 on the shaft 72 and through the medium of the gear 76 on the'shaft 72, the gear 77 will be moved in the opposite direction. This direction of r0 tation of the gear 77 will rotate the gear 80 which in turn will raise the segn'ient 81 and move the extren'iity' 84 of the arm or lever 82 toward the axis of rotation of the cam 90. The normal position of the cam 90 is such that the low portion thereof will be in the path ofmovement of the extremity 84 of the arm or lever while the high portion thereof will project into the bifurcated portion 85 of the arm or lever as shown clearly in Figs. 3 and 4. As the typewriter carriage advances, the arm or lever 82 will be automatically adjusted. It .will therefore be manifest that in order to return the type writer carriage 42 to itsinitial or starting" position from any point to which it has ad vanced, all that is necessary is to raise the extremity 84 of the arm or lever 82 to lower the segment 81 and this may be accomplished by rotating the cam 90 about its axis of rotation. In order, therefore, to automatically control the rotation of the cam, suitable mechanism is provided which will now be described, reference being had particu larly to Figs. 3, 4 and A running shaft 91 journaled in suitable supports 92 is provided and may derive its motion from any suitable source of power This shaft is preferably arranged parallel with and adjacent to the shaft 88. A stub shaft 93 is arranged with one extremity adjacent one extremity of the running shaft 01 and the other extremity is journaled in a suitable hearing 01/ The shaft 0?, is connected to the running shaft 01 for rotation therewith tln'ough the medium of a gear 05 on the shaft 03 which meshes with a gear 00 on a supplemental shaft 07 and this shaft 7 is in turn connected directly with the shaft 91 through the medium of a gear 98 meshing, with a gear 00 on the. shaft 01. Mounted loosely upon the shaft 03 is a gear 100 which meshes with a gear 101 fast on the shaft 88 to which the cam 00 is connected so that when the gear 100 is rotated the shaft 88 will be rotated through the medium of the gear 101. which-rotation will rotate the cam 00. in order that the gear 100 may he locked for rotation with the shaft 03. a clutch mechanism is provided which consists of a disk 102 (see also Fig. 7) secured to the gear 100 and which disk is also loosely mounted on the shaft 93. A star or toothed wheel 103 is secured fast to the shaft 93 and rotates therewith and a dog or pawl 104 is pivotally mounted on the disk 102 so that one extremity 105 will engage the star or toothed wheel 103 and thereby lock the disk 102 to the shaft and consequently the gear 100. An elastic member 100 is'also provided which tends normally to move the teeth 105 of the dog 101 into engagement with the extren'iity of the star or toothed wheel. The dog or pawl 10% is provided with a shoulder 101 which is adapted to engafie an arm 108 pivotally supported as at 10!). ll'hen the extremity of this arm 108 is moved into the path of movement of the shoulder 10? of the dog 104, the latter will he moved out of engagement. with the star or toothed wheel 10?) to release the gear 100 but when the extremity of the arm 108 is moved out of engagement with, or the path of movement of. the shoulder 10?. the elastic member 100 will move the extremity the dog into engagement with the star or toothed wheel 103 to lock the gear 100 .to the shaft 93.

A dog 110 is provided and is controlled by an elastic member 111 which latter tends lock the gear normally to move the extremity of the dog into a notch 112 in the periphery of the disk 102 to lock the disk against overthrow. An elastic member 11?) tends normally to hold the extremity of the arm 108 into the path of movement of the shoulder 107 on the dog,

and this arm is adapted to he moved out of engagement with the shoulder 107 so as to 100 to the shaft, at the will of the operator, by means of a suitable operating key llsarranged in a convenient position for the operator. It will therefore be manifest that the rotation of cam 90 is controlled at the will of the operator by the,

action of the key 111. When the key 114 is released, the elastic memher 113 will return the latter and will also adjust the arm 108 to automatically release or unlock the gear 100 with respect to the shaft 93 without interrupting the rotation of the shafts 91, 93. As has been already stated the extremity 81 of the arm 82 during the advancement of the typewriter carriage is moved toward the axis of rotation of the cam 90 and whenever the cam 90 is rotated in the manner just set forth, the arm 82 will be moved toits normal or initial position to return the carriage from any point to which it, has advanced.

In the present'exemplification of the invention the traveling actuating mechanism of the registers is adapted to be advanced simultaneously with the typewriter carriage during nine steps of advancing movement of the typewriter carria e and to be automatically returned to its initial position during the tenth step of theadvancing movement of the typwriter carriage, and suitable mechanism for accomplishing this relative movement of the parts will now be, described, reference being had particularly to Figs. 3 and 8 to 16 inclusive.

Loosely mounted upon the shaft 15 and secured to the gear 47 for rotation therewith is a gear 115 with which a toothed segment 116 on an arm 117 meshes. This arm is pivotally supported intermediate its ends as at 118 and the free end 119 of the arm is adapted to be moved into and out of the path of movement of a cam 120 (see particularly Figs. 3, 10 and 11),

p which cam is loosely mounted upon a shaft. 121 having suitable bearings 122. The shaft 121 is rotated from a running shaft 123, which latter receives its motion from any suitable source. A gear 124 is secured to the shaft 123 for rotation therewith and meshes with a companion gear 125 on the shaft 121. The cam 120 is locked for rotation with the shaft 121 by.

means of a suitable do 126 pivotally su ported on a disk 127 which latter is loose y mounted on the shaft 121 and is connected with the cam 120 for rotation therewith. A star or toothed wheel 128 is secured to the shaft 121 for rotation therewith and the dog 12G cooperates with this star or toothed wheel for locking the parts to the shaft. An elastic member 129 tends normally to move the dog 126 of the star wheel and a'shoulder 130 is provided on the dog. It will thus be seen that when the cam 120 is locked to theshaft 121, itwill lie-rotated by the shaft and when the extremity 119 of the arm 117 is engaged by the cam 120, the arm will be rockedabout its point of pivotal support 118 to move the into engagement with the teeth 'member 129 will adjust the dog 126 to lock as to move a shoulder or and as the latter follows up the movement of the shaft 45 so as to move therewith during the advancing movement of the typewriter carriage it will be manifest that the traveling actuating mechanism will also be advanced through the medium of the arm 37 and as the gear 115 is rotated the segment 116 will be moved and consequently the arm 117 will be rocked about its point of pivotal support and the extremity 119 of the arm will be moved into a position to be engaged by the cam 120.

A releasing dog or arm 131 is pivoted intermediate its ends as at 132 and its extremity 133 is provided with a shoulder adapted to engage the shoulder 130 on the dog 126 to hold the latter out of engagement with the star or toothed wheel 128. When this shoulder 133 is moved out of engagement' with the shoulder 130, the elastic the cam 120 to the shaft 121'. The normal position of the arm 131' is that shown in Fig. 11 so that the cam 120 will unlock with respect to the shaft 121.

As the typewriter carriage advances the arm or lever 37 will be moved int'he direction indicated by the arrows in Fig. 3 so projection 134 on the segment 48 toward a pin or projection 135 on a link 136, which latter is supported by a. bracket 137 for adjustment with respect thereto by means of a fastening pin 138 carried by the link 136 and which passes through a slot 139 in'the bracket 137. One end of this link 136 is pivotally connected as at 140 to the free end of the arm 131 and the pin or projection 135 is located at the free end of the link so as to projectinto the path of movement of the shoulder 134 on the segment 48. The link length that the segment 48 may be advanced nine steps during the nine steps of advancement of the typewriter carriage but during the tenth step of advancement of the type- Writer carriage, the shoulder 134 will be moved into engagement With the pin or projection 135 on the link 136 so as to shift the link and rock the arm 131 to release the dog 126 and thereby lock the shaft 121 for rotation therewith. As the traveling actuating mechanism'is thus re turned the segment 48 will be moved in the opposite direction or the direction opposite to that indicated by the arrows in Fig. 3, to move the shoulder 134 away from the pin or projection 135 and when the segment is thus adjusted the link 136 will be returned to permit the shoulder 133 on the arm 131 to be moved into the path of movement of the shoulder 130 of the dog 126 to trip the latter, by means of an elastic member 140 such as a spring or the like.

After the traveling actuating mechanism has been returned to its initial or starting 136 is of such acam 120 to the position, the segment 48 of the arm 37 will have assumed the position shown in Fig. 3 and in order to prevent the motor compris' ing the gear 63 and the spring 67 from starting or' moving the traveling actuating mechanism in a direction to advance the latter while the typewriter carriage is being returned so as to hold the actuating mechanism in its initial position, a stop 141 is provided (see particularly Figs. 3 and 18), which consists of an elongated member preferably secured to the arm 37 to form a shoulder 142. A. dog is pivotally supported upon a fixed support 144 and moves between suitable guides 145 so that itsextremity 146 will assume, a position in the path of movement of the shoulder 142 and anelastic member 147 is provided which tends normally to move this extremity 146 into such position to be engaged by the shoulder and thereby lock the traveling actuating mechanism against movement. This dog 143 is connected through the medium of intermediate connecting mechanism d'esig nated generally by the reference numeral 204 with the escapement mechanism 7 of the typewriter carriage, so that each time a key is actuated and the typewriter carriage escapes, the dog 143 will be rocked and in the event that the extremity 146 stands within the path of movement of the shoulder 142, the'dog will be raised to permit the segment 48 andthe arm'37 to be advanced. After the shoulder 14-2 has passed the extremity 146 of the dog; this extremity will engage and rest upon the top of the member 141. The connection 204 may he formed of a link 205 having a pinand-slot connection with the dog 143, and an arm 206 connected to the link 205 and fixed on the arm 16 'of the escape-mentmechanism, so as to swing therewith at the actuation of any of the character keys. The lost motion between the link 205 and the dog 143 is provided so that the movement of the cscapement mechanism 7 will not be interfered with in case the dog 143 is riding on top of the stop 141.

It will therefore be manifest, that during each tenth step of advancing movement of the typewriter carriage the traveling aC- tuating mechanism will be automatically returned to its initial or starting position, and in order to permit the tt' icw'iitei' carriage ,to be returned to its initial or starting position independently with respect to the traveling actuating mechanism and without returning the traveling actuating mechanism, mechanism. mus; be provided if=1 r preventing the automatic peration of the re turning mechanism of the traveling acttuzting mechanism, which will now h the purpose already set forth by means hf a se ent 148, (see particularly Figs. 3, 8 and l g which is provided with teeth 149 meshing with the spaced rings or ribs 58 on the clutch member. This segment is secured to a rock shaft 150 which latter is journaled in suitable bearings 151 and is provided-with a segment 152 secured thereto (see also Fig. 4). This segment 152 meshes with a segment 153 on an arm 154 pivoted intermediate its ends as at 155 to a support 156. The arm 154 is preferably arranged adjacent to and parallel with the arm 82 so that the extremity 157 of the arm will terminate adjacent the shaft 88 (see also Fig. 7) which extremity is provided with a lateral projection 158 coiiperating with a disk or cam 159 and an elastic member 160 tends normally to hold the extremity 157 of the arm 154 in engagement with the periphery of the cam.. This cam 159 is secured for rotation withv the shaft 88 and'the high part of thecam 159 is so disposed with respect to the high part of the cam 90 that when the shaft 88 is rotated motion will be imparted first to the arm or lever 154 to rock the segment 152, rock shaft 150 and segment 148 to shift the. clutch member 49 on the shaft 45 so as to present the smooth periphery 53 of the clutch member to the dogs or pawls 61 and thereby unlock the gear 47 with respect to the shaft 45. A continued movement of the shaft 88 in the same direction will cause the'cam'90 to then rock the arm 82 so as'to rotate the shaft 72 and shaft 45 in a direction to return the typewriter carriage '42.

When the low part of the cam 159 is in proximity to the projection 158 on the arm 154, the elastic member 160' will rock the shaft 150 in the opposite direction and consequently move the segment 148 in the opposite direction to shift the clutch member 49 into a position to again lock the gear 47;-

to they shaft 45.

As has already been stated, the. traveling actuating mechanism will be automatically returned during the tenth step of advancing movement of the typewriter carriage by the engagement of the shoulder 134 with the pin or projection 135 on the link 136 which shifts the arm 131 so that the cam 120 will be locked to the shaft 121. Therefore in the event that it is desired to permit the traveling actuating mechanism to remain in the position to which itIhas advanced and to return the typewriter carriage independently with respect to thetraveling actuating mechanism it is necessary to prevent the eng'igement of thejshoulder 134 -with the pin or projection 135 5n the link 136 as the engagement 'of thesepar'ts, during this operation might cause damage. to the machine. Mechanism istherefore provided to arrest the movement of the segment 48 before the shoulder 134 engages the pinor projection 135 on the link 136 and preferably comprises an arm 161 (see particularly Figs. 3, 8, 15 and 16) which is connected to the shaft 150 and is sodisposed with respect to the segment 148 that when the latter is adjusted to shift the clutch member 49 on movement of a second shoulder 162 on the segment 48, and which shoulder engages the arm before the shoulder 134 will engage the pin or projection 135 on the link 136. The

. 11) for holding the disk 127 in position when the shaft 45 to unlock the gear 47 there' from, the arm will hemoved into the path of unlocked from the shaft 121 and an elastic member 165 is also provided which tends normally to hold the dog 163 against the periphery of the disk. From the above description it is thought that the operation of all the parts will be clearly understood, but briefly stated it is as follows:

As the typewriter carriage 42 advances motion will be imparted to the shaft 45 and the arm 37 will be rocked about its pivot 33 to advance the carriage 28 upon which the traveling actuating mechanism of the totalizers is'mount-ed. The carriage 28 will be ad.- vanced step by step by the advancement of the typewriter carriage 42 during nine step-4 of advancing movement of the latter and as the arm 37 is moved about itspivot 38 the shoulder 134 on the segment 48 will be moved toward the pin or projection 135 on 1 the link 136. During this movementof the parts the arm 117 will be rocked about its point of pivotal support 118 to move the extremity 119 thereof'into the path of movement of the cam 120, which latter is loose on its shaft. During the tenth step of advancing movement of the typewriter carriage the shoulder 134 will engage the pin or projection 135 on the link 136 and shift the latter to ,rock the arm 131, thus releasing the dog 126 and locking the cam 120 to the shaft 121. Thus locked motion will be imparted from the running shaft 123 to the cam 120 and the arm 117 will be rocked in the opposite direction to rotate the gear 47 in the opposite direction, which movement is permitted by means of the dogs or pawls 61. sliding around the periphery of the portion 54 of the clutch member 49. This reverse movement of the gear 47 will rock the arm 37 in the opposite direction and return thecomputing carriage 28.

During the advancing movement of the typewriter carriage motion will also be haa series of dittcrent nui'nbers of different (:01-

the typewriter carriage.

any point to which it has advanced, the key- 114 may be actuated which will rock the arm 108 to release the dog 104 to lock the gear 100 to the running shaft 93. Thus locked the gear 100 will rotate the cam 90- to shift the arm 82 in the opposite direction and thereby rotate the shaft 72 in the opposite direction as well as the shaft 45 to return the typewriter carriage. d/ hen the key 114 is actuated to return th typewriter carriage, the rotation of the shaft- 88 will also rotate the cam 159 andthis will rock the shaft 150 to shift the clutch member 49 to release the gear 47 and at the same time move the arm 161 into the path of movement of the shoulder 162 on the segment 48 to arrest the movement of the segment before the shoulder 134 strikes the projection 135 to prevent the cam 120 from being locked to the shaft 121.

The device is also capable of cross-addition. For example, we may start with the carriage at the right and write a series of digits comprising a number in thefirst column on the work-sheet, and these digits may be run up successively even on a single computing register or totalizer 25, as the traveling ,actuating mechanism, including the master wheel 32, moves step by step with the step-by-step letter-feeding movement of When the entire number inthis first column has been written, the limit being in this case nine digits corresponding to nine step-by-step movements of the typewriter carriage, then a further movement of the typewriter carriage will cause the automatic return of the com uting carriage with its master wheel,

so mat the computing mechanism is ready to run up the digits of a fresh number. The typewriter carriage,-however, can travel on without returning to bring the next columnar space on the work-sheet up to the printing point when the next number, comprising a series of digits, can be inscribed thereon and concomitantly run up on the computing register or totalizer 25. This can be repeated within the limits of the w'ork-sl1eet and the travel of the typewriter carriage. Vixen the line is completed wehave crossadded in the computing register or tot'alizer,

umns arranged in the same horizontal line. When the end of the line has been reached, the key Hi can be depressed to enable a complete return movement of the carriage to its original starting position. The type.- writer planar can then he spacedto bring a fresh line of the work-sheet up to the print.- ing point and the operation repeated as often as desired. By this arrangement, then,

we may .have repeated vibrations of the traveling element of the computing mechanism durlng one single continuous travel of the typewriter carriage from left to 26, 1906, and 504,595. filed June 26, 1909.
